Li7-x+y(La3-ySry)(Zr2-xMx)O12 (1) In the formula (1), x and y satisfy 0.20≤x<1.50 and 0.00<y<0.30, and M is two or more types of elements selected from the group consisting of Nb, Ta, and Sb.
Claims5
A solid electrolyte, represented by the following compositional formula (1):
- Li7-x+y(La3-ySry)(Zr2-xMx)O12 (1)
- wherein x and y satisfy 0.20≤x<1.50 and 0.00<y<0.30, and M is two or more types of elements selected from the group consisting of Nb, Ta, and Sb.
A method for producing a solid electrolyte comprising:
- a mixing step of mixing multiple types of raw materials containing metal elements included in the following compositional formula (1), thereby obtaining a mixture;
- a first heating step of subjecting the mixture to a first heating treatment thereby forming a calcined body;
- and
- a second heating step of subjecting the calcined body to a second heating treatment thereby forming a crystalline solid electrolyte represented by the following compositional formula (1):
- Li7-x+y(La3-ySry)(Zr2-xMx)O12 (1)
- wherein x and y satisfy 0.20≤x<1.50 and 0.00<y<0.30, and M is two or more types of elements selected from the group consisting of Nb, Ta, and Sb.
